This bill mandates that school athletic teams be explicitly designated based on the biological sex at birth of the participants, with separate categories for males, females, and coed/mixed teams. It prohibits biological males from participating in athletic teams or sports designated for females. The determination of a student's sex for eligibility in sports is to be based on the student's original birth certificate or a certificate issued upon adoption, which must correctly state the student's biological sex at birth. If the provided birth certificate is not original or does not indicate sex at birth, the student must present other evidence of their sex at birth at their own expense. The bill requires the state board of education, local school boards, and governing bodies of public charter schools to adopt policies to ensure compliance with these provisions.

The bill also establishes various causes of action. A student who is deprived of an athletic opportunity or suffers harm due to a school's violation of the new rules can seek injunctive relief, damages, and other legal remedies. Similarly, students facing retaliation for reporting violations, and schools harmed by violations, can take legal action. All civil actions must be initiated within two years after the harm occurred, and successful claimants are entitled to monetary damages, attorney's fees, and other appropriate relief. The act includes a severability clause to maintain the validity of the rest of the act if any part is found invalid, and it is set to become effective 30 days after its passage, with an effective date of August 18, 2024.
